The five zang viscera

especially the liver

spleen

lung and kidney

are not named arbitrarily

but are determined by Xiang（象）-thinking. The side of these Chinese character such as Gan（干） of the liver（肝）

Bei（卑） of spleen（脾）

Fu（巿） of lung（肺） and Qian（臤） of kidney（肾） not only represent the pronunciation

but also are the main source of the meaning of four zang viscera. According to the anatomical structure observation and the thought of the five internal organs

the ancients used the method of image-like thinking to use the specific image of the "Gan"and "Fu"in life and the specific function of "Bei"and "Qian"images were used to name zang viscera.In view of this

the close relationship between object thinking and the establishment of Chinese medicine can be deeply understood.
